Abstract: <p>A species of concern is caribou (Rangifer tarandus), a species in decline across most of the circumpolar North, including the island of Newfoundland. Resource exploitation across caribou ranges is projected to accelerate in the coming decades as oil extraction, roads, forest harvesting, and mining encroach upon their habitat. Hydroelectric corridors, in particular, are anticipated to… more Full Text: THE EFFECTS OF HYDROELECTRIC CORRIDORS ON THE DISTRIBUTION OF FEMALE CARIBOU (Rangifer tarandus) ON THE ISLAND OF NEWFOUNDLAND A Thesis Submitted to the Committee on Graduate Studies in Partial Fulfilment of the Requirements for the Degree of Master of …

Abstract: <p>The flavohemoglobin in Giardia intestinalis (gFlHb) is the only known protozoan member of a protein class typically associated with detoxifying nitric oxide (by oxidation to nitrate) in bacteria and yeast. Mutants of the B10 tyrosine (Y30F) and E11 leucine (L58A), conserved residues thought to influence ligand binding, were expressed and studied using Resonance Raman (RR) spectroscopy.… more Full Text: Mutation of the B10 Tyrosine and E11 Leucine in Giardia intestinalis Flavohemoglobin A thesis submitted to the Committee of Graduate Studies in partial fulfillment of the requirements for the degree of Master of Science in the Faculty of Arts and Science …

Abstract: <p>Giardia intestinalis is a protozoan parasite that causes waterborne diarrheal disease in animals and humans. It is an unusual eukaryote as it lacks the capacity for heme biosynthesis; nonetheless it encodes heme proteins, including three cytochrome b5 isotypes (gCYTB5s) of similar size. Homology modelling of their structures predicts increased heme pocket polarity compared to mammalian… more Full Text: ELECTROCHEMICAL CHARACTERIZATION OF GIARDIA INTESTINALIS CYTOCHROMES b5 A Thesis Submitted to the Committee on Graduate Studies in Partial Fulfillment of the Requirements for the Degree of Masters of Science in the Faculty of Arts and Science TRENT …

Abstract: <p>The present thesis explores the cold flow properties of biodiesel and the effect of vegetable oil derived compounds on the crystallization path as well as the mechanisms at play at different stages and length scales. Model systems including triacylglycerol (TAG) oils and their derivatives, and a polymer were tested with biodiesel. The goal was to acquire the fundamental knowledge that… more Full Text: MITIGATING COLD FLOW PROBLEMS OF BIODIESEL: STRATEGIES WITH ADDITIVES A Thesis Submitted to the Committee on Graduate Studies in Partial Fulfillment of the Requirements for the Doctor of Philosophy in the Faculty of Arts and Science TRENT UNIVERSITY …

Abstract: <p>Many print sources from 1680 to 1730 depicted bawds and witches as figures of transgressive elderly femininity. They were often described as having roughly the same anti-social behaviour, age, and gender. Both witches and bawds were seen as seducing innocents into a life of sin, associating with the </p><p>devil, and acting lustful and unmotherly. Furthermore, they were… more Full Text: WITCHES AND BAWDS AS ELDERLY WOMEN IN ENGLAND, 1680-1730 A Thesis Submitted to the Committee on Graduate Studies in Partial Fulfillment of the Requirements for the Degree of Master of Arts in the Faculty of Arts and Science.

Abstract: <p>This thesis explores the use of 1-butene cross metathesized palm oil (PMTAG) as a feedstock for preparation of polyols which can be used to prepare rigid and flexible polyurethane foams. PMTAG is advantageous over its precursor feedstock, palm oil, for synthesizing polyols, especially for the preparation of rigid foams, because of the reduction of dangling chain effects associated with… more Full Text: Synthesis of Lipid Based Polyols from 1-butene Metathesized Palm Oil for Use in Polyurethane Foam Applications A Thesis Submitted to the Committee on Graduate Studies in Partial Fulfillment of the Requirements for the Doctor of Philosophy in the Faculty …

Abstract: <p>Damage to the hippocampus (HPC) typically causes retrograde amnesia for contextual fear conditioning. Reinstating the conditioning over several sessions, however, can mitigate the retrograde amnesic effects. Reinstatements, thus, establish a sufficiently strong memory in non-HPC systems to no longer require the HPC for expression, meaning that it has become HPC independent. This thesis… more Full Text: NON-HIPPOCAMPAL MEMORY SYSTEMS CONTRIBUTING TO REINSTATED CONTEXT MEMORY A Thesis Submitted to the Committee on Graduate Studies in Partial Fulfillment of the Requirements for the Degree of Master of Science in the Faculty of Arts and Science TRENT …
